The Quiet Liner™ – Advanced Acoustic and Thermal Duct Insulation is engineered to deliver comfort, performance, and sustainability in HVAC systems. Made from recycled cotton fibers, this fiberglass-free HVAC acoustic liner provides both noise absorption insulation and thermal efficiency, making it a reliable choice for projects focused on occupant well‑being and environmental health.
With its durable black scrim facing, Quiet Liner™ functions as a black-faced acoustical absorber while resisting microbial growth thanks to an EPA‑registered antimicrobial treatment. As a Class A fire-rated duct liner, it meets critical safety standards while maintaining low air-resistance acoustic insulation to support airflow and system efficiency.
This cotton fiber acoustical absorber is formaldehyde‑free, non‑allergenic, and non‑irritant, ensuring healthy indoor air quality. It is ideal for ductwork acoustic treatment in offices, schools, healthcare facilities, and industrial spaces, where both mechanical room sound control and thermal efficiency acoustic insulation are essential.
Available in rolls and sheets, Quiet Liner™ serves as a versatile solution for retrofit ductwork acoustic treatment, industrial and commercial HVAC sound control, and green building acoustic insulation (LEED‑friendly) applications. By combining natural fiber acoustics with proven durability, Quiet Liner™ offers professionals a dependable way to achieve excellent noise absorption (high NRC options) and long‑term system performance.
